Strange action from MTH WM BL2

Yes I have had that same problem with my new AC4400 cw Norfolk Southern engines #4002 & 4004. Started them up and had that loud staticky sound. Shut them down and restarted and they ran fine.  I have only run each one once so far but it happened to both engines. After the restart probably ran each engine about 15 minuets and all was good. 

We must be the only two that has had this problem

I find my ps3 loco sometimes do strange things, and need a good night's sleep before they'll work.

I'm not an MTH expert, but I do have some PS2/3 here and there, and have found that they will occasionally need a re-boot (they are little computers, after all). I have had an MTH loco or two experience a transitory derailment, then sit and start making noises like one of the old Daffy Duck cartoons (kind of a version of yadda-yadda-yadda-...really) until I reboot it.

My Lionel electronics are not nearly as entertaining. Thankfully.

I installed a PS3 board into an engine and swapped the sound files and the chain files. After the first cycle of power changing the sounds, the volume went thru the roof when I pressed shut down. I then changed the chain files and the board made the reset beeping sounds when I cycled power the first time.

 Since then, everything has been fine. So maybe there's some type of reset that has to take place? I can only suggest after reading your posts that cycling the power seems to be the answer. Why the board resets in your case(s), I'm not sure? Was the engine run much? Long times in between runs? First time power was applied?

BTW, I am not a tech, I just play with these!

Both mine were when I first took them out of the box and fired them up

HI Engineer Joe.

My BLT2 was fairly new and run very little. It did sit idle for several weeks before I ran it and experienced the loud strange sounds.

Thanks
